HERMAN Gr. DOELLINGER, OF DAVENPORT, IOW'A, ASSIGNOR TO HALLIGAN CANDY COMPANY, OF DAVENPORT, 301V A, A CORPORATION C F IOWA.

To all whom it may concern: 7

Be it known that I, HERMAN G. DOELLIN- GER, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Striping-Machines, of which the fOllOWing is a full, clear, and exact description.

My invention relates to machines for decorating chocolatecreams and bonbons, and particularly the machine for which Letters Patent of the United States were granted to me March 5, 1918, N 0. 1,258,322.

In machines of the kind above specified, the liquid chocolate is fed to pumps that force the same through the striping devices and this chocolate is obtained from the same source as the chocolate in which the blanks are dipped or sprayed. Thischocolate is thin and soft, and when it issues from the striping devices it is so thin and hot that it merges into the chocolate coating on the blanks and practically disappears or at least produces a very vague effect.

It is the object of my invention to overcome this objection, and to make the design produced. by the striping stand out distinct and clear on the blanks without requiring the expenditure of any more time or labor. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings:

Figure 1 is a vertical longitudinal section through the portion of a striping machine 7 embodying my improvements.

Fig. 2 is a transverse line 2-2, Fig. 1.

In the accompanying drawin A represents an inverted rectangular i m-shaped hopper or tank, the closed upper end of which has a suitable inlet opening a, through which hot liquid chocolate may be poured into it. The side-walls of this tank are provided with a water jacket B which reduces the temperature of the chocolate therein and makes it thicker, and the lower edges of said tank are provided with outwardly projectsection taken on ing flanges to'enable it to be mounted upon and connected to corresponding flanges projecting from the upper edges of a rectangular casing C in which a series of rotary gang pumps operate. The water jacket B is provided with the inlet and outlet pipes B and B through which the cooling me- Specification of Letters Patent.

dium is led into and out of the water jacket B.

This gang pump mechanism is fully described in Letters Patent of the United States granted to me March 5, 1918, No. 1,258,322, and a detailed description herein of this mechanism is, therefore, considered unnecessary. It is suilicient to state that the ends of one or both of the parallel pump shafts D, D, extend through their bearings in the end of this casing, and at one end the driven shaft is provided with a pulley (l through the medium of which said shafts are driven and at the other end one of said shafts is provided with a comparatively arge gear 0.

The tank is provided, preferably, midway between its ides and near the bottom thereof with a longitudinally extending shaft E, and this shaft is provided with one or more series of open paddles 6. These series each comprisethree or four equi-distant paddles,

these discharge pipes are connected by vertical pipes H with rearwardly extending pipes I that lead to and discharge into the upper end of the tank. Between the upper end of pipes H and the ends that discharge into the tank, pipes I are provided with valves J that screw vertically down into and close the bores thereof or control the flow of chocolate back into the tank. The forward ends of pipes I are suitably constructed to permit the ends of flexible pipes K to be attached thereto, and the lower ends of pipes K are provided with nozzles that are adapted to be manipulated by operators to stripe or decorate the chocolate blanks as they travel ast on the wire apron M that travels longitudinally underssthe pump casmg.

lVhat I claim asnew is:

1. In a device of the class described the combination of a receptacle for containing coating material for confections, a pump, a passage leading from the pump through V v -1,331-,c25

which the coating material from the puinp is discharged, a tubular connection connected with said passage, one end of said tubular connection being connected with the re- 7 ceptacle and the opposite end thereof being provided with a flexible connection whereby the coating material may be discharged from the passage,

2. In a machine of the class described, the combination of a receptaclefor containing coating materiahfor confections, a pump, a

passage connected with the pump atlirougn which the coating material from said pump is discharged, a tube connected with the-passage, one end of the tube having a conncc tion with the receptacle, aflexible connection attachedto the opposite end ofsaid tube, and a acket surrounding said receptacle.

3. Ina machine of the class described, the combination of a receptacle forcontaining coating material for confections, a pump, a

7 end, a flexible connection.attachedto v the opposite end of'said tube, and a jacket-stir rounding the receptacle.

, 4:. In a machine of the class described, the,

combination of a V receptacle for: containing coating material for confect ons, stirr ngde- 'VlCeS arranged inth'e receptacle, a-puinp, a

passage leading from the pump through which the coating material 'i'romthe pump is discharged, a tube connected with the passage, one end of the tube haifingaconnection with the receptacle, a flexibleconnection attached to the opposite end of said tube and a jacket surroundingthe receptacle.

5. In a machine: oftheclass described, the

combination of -a recepta'cle for containing 1 coating. material forIconfections,.stirring devices arranged in the receptacle, a 7 pump, a passage leading from 'thewpump; tln'ough which the co ati-n ,inaterial, from-the vpump is discharged, 'a tube connected with the; pas,-

sage, one end of the tube lRLViHg ESgGODJI LGC-V tion with; the: receptacle, a (valve arrangedbetween the diseharge; passage froiii.jthe pump and the receptacle, a flexible connection. leading from the opposite end of the tube 'andra acket surrounding the receptacle. .1
